The object of the invention in general is to provide a novel circuitbreaker.

Further, the object is to provide a circuit breaker which is selectivelyoperated by a pattern card.

Still further, the object of the invention is 1 to provide a circuitbreaker which is mounted in a manner to facilitate the movement of apattern card back and forth relative to the breaker.

Another object is to provide a machine in which the conductorsconnecting the duplicator with punch selector magnets are housed in animproved manner and are given a fan arrangement as they pass to thedetecting portion of the du licator.

Still. another ob ect is to. provide means forbreaking the duplicatorcircuit when a pattern card is removed from or placed in the duplicator.

Various other objects and advantages of my invention will be obviousfrom the following particular description of one form of mechanismembodying the invention or from an inspection of the accompanyingdrawing; and the invention also constitutes certain new and novelfeatures of construction and combination of parts hereinafter set forthand claimed.

Fig. 6 is a vertical section through the punch part of the machine.

Fig. 7 is a detail of theescapement means. Fig. 8 is a detail of thecard carriage moving means, and v F ig. 9 is a circuit diagram of themachine.

The machine is provided with a main frame 1 and arranged for convenientright handoperation by a handle 2 having a normal position at the righthand end of the machine and being mounted for leftward movement alongthe side of the machine. Whenever the handle 2 is moved tothe left' inthismanner, a statistical card 3 is withdrawn by a picker 4 from thebottom of a pack in a magazine 5 and advanced to be operated upon bypunchingmechanism 6. Such leftward actuation of the handle'2 also servesto move a card carriage 7 to the right' to a position to receive thecard 3 when the picker 4 reaches the end of its leftward, movement. Thecard is then punched columnby column as required and the card carriagemoved step by step to theleft. When the punching of the card iscompleted andthe carriage 7 has reached the end of its movement, thepunched card may be removed andthe operation repeated.

The punching mechanism 6 may be operated normally by means of numeralkeys 8 7 'or may be controlled by a duplicator 9 in accordance'wi th'theperforations of a pattern member which. may be a previously punched card3P. Such pattern memberis supported by the card carriage 7 and is movedthrough the du licator concomitantly withthe movement of a card throughthe punching mechanism.

The handle 2 may be used to actuate the card carriage 7 .To this end thebracket 16 on which the handle 2 is secured extends through alongitudinal slot 32 (Fig.- 8) in a tube 33 and is secured toa rod 34slidable in said tube. ,The slot 32 is of sufiicient length to permitthe necessary movement of the handle 2 and the tube 33 is supported onthe main frame 1 by slotted brackets35 as shown in Fig. 3. Adjacent the.extreme leftward position of the handle 2, the tube 33 is cut away atthe top to permit'teeth 36 on the 90 upper side of the rod to mesh withthe teeth of a pinion 37 and a gear 38. Thepinion 37 is mounted on ashaft 39 (Fig. 8) on which is fixed a hub 40 connected by a spiralspring 41 with a cup 42 secured to the frame 1. As the handle 2 is movedto the left the spring 41 is placed under tension and upon the releaseof ing connection with a shaft-46 an slidable therealong into and out ofengagement with the member 43. At itsother end the shaft 46 is providedwith a gear 47 fixed thereon and meshin with teeth on the lower edge ofa rack 48 w ich may be considered as forming a part of the card carriage7.

7 To control the clutch member provision is made of a yoke 49 pivotallysupported by means including a bracket 50 fixed on the main frame, andhaving 'at. its free end elements 51 projecting into the groove 52. The

yoke 49 is urged in a clutch breaking direction by aspring 53 and isalso controlled by means of a yoke 54 pivoted to turn aboutthe sameaxisas yoke 49 and having a finger .piece 57. Joining the yokes 49 and 54 isa spring 62 havin a greater effect than spring 53, so that uponlepression of the finger piece 57 the clutch'member 45 will be shiftedto operative position. In this connection it shouldbe notedthat theteeth of the clutch members 43 and 45 are so inclined that when inoperative relation a leftward movement of handle 2 will transmit throughmeans including the clutch 44 power to move the card carriage 7 to therightto receive a card 3 positioned by the picker 4 in the punching'mechanism 6. If, however, the handle-2 is moved to the right the teethof the clutch members 43 and 45 will ride over each other and force theclutch members apart.

The clutch 44 is controlled by the rod 34 and to this end the yoke 54extends through .anotch in thetube 33 and engages the lower surface ofthe rod 34. When the rod 34 is in its retracted position the yoke liesin a notch 63 (Fig. 5) inthe' bottom of the rod 34 and the spring 53 iseffective to disconnect, the clutch. This enables actuation of the cardcarriage while the picker mechanism remains at rest. The notch 63 has aninclined wall at the right so that, upon movement of the handle 2 to theleft theyoke will be depressed and the clutch member 45 moved intooperative relation with clutch member 43. p

Due to the engagement of the rod 34 with the lower side of gear 38 andof the rack 48 with the upper side of the gear 47 movea drivment of thepicker4 to the left with a card for presentation to the punchingmechanism 6 willbe accompanied by a rightward movement of the cardcarriage 7 into a position to receive the card from the picker 4. As indicated in Fig. 5 the rack 48 is'carried by means of grooved rollers 64running on a rail 65 mounted in the main frame and an adjacent member 66with a flange overlying the heads -of the studs which carry the rollers64. The movement of the carriage 7 to the right may be limited by meansof a suitable stop 67 (Fig. 3) in the path of the end of the rack 48.

In addition to the rack 48 the card carriage comprises a forwardlyprojecting arm 69 (Fig. 3) having at its forward end a device 70 toengage the rear edge of a card 3 in its passage through the punchingmechanism 6. Such device 70 when in effective position with respect tothe rear edge of a card lies in a groove 71 which also receives a device72 to engage the forward edge of a card in the card carrier andsupported on a member or arm 73 which is secured to the rack 48 andextends. to the rear thereof to support a device 74 for engaging theforward edge'of a card resting on the top of the duplicator which formsa table 74a. The device 74 travels in a groove 7 5 in the table 74a andthis groove also serves to'receive a device 76 for holding the other endof the pattern card and which is mounted on the rear end of an arm 69asecured to the rack 48 at its rear face.

- When it is desired to punch the lowest card in the magazine 5, thehandle 2 is moved to the left to advance the picker 4 and-move such cardinto the punching mechanism. As soon as the movement of the rod 34 totheleft is begun the inclined right wall of the notch 63 will cam downthe yoke 54 and shift the clutch member 45 into engagement with theclutch member 43 thus connecting the gears 38 and 47 so that theleftward movement of the rod 34 will effect a movement of the rack 48and carriage 7 in the opposite direction to a position to receive thecard from the picker 4, the card passing beneath the device 70 to aposition to be engaged oper- A atively thereby.

Such rightward movement of the rack 48 is effected against the action ofa spring drum 83 connected directly with a gear 84 meshing with theteeth on the lower side of said rack 48 (see Figs. 1 and 7). The top ofthe rack 48 is also provided with teeth 85 inclined toward the left endof the machine and when the carriage 7 has reached the limit of itsmovement it is held there by engagement of one of said teeth by astepping pawl'or dog 86 loosely mounted on a pivot 87 is a bracket 88mounted on a fixed part of the machine.

At this time the first column of the card to be punched will lie beneatha row of punches -in a die plate v93.

The punches 89 are normally held in raised position by springs 94interposed between the enlarged heads thereof and the stripper memberwhich is provided with openings to receive the lower ends of saidsprings. Resting on the upper ends of said punches are interposers 95supported at their rear ends on a cross member 96 and resting againstthe lower face of an overlying plate 96a so that they prevent furtherupward movements of said punches. The interposers 95 are so notched attheir forward ends that when they are in their normal positionsdepression of a plate 97 against a spring'98 will merely move member 99of the depresser 99a into such notches.

When. however, any numeral key 8 is depressed it willactuate a bellcrank 100 against the tension of 'a spring 101. the forward arm of eachbell crank having a rounded head fi tting into a notch in the shank ofthe kev and v the upright end having a pin 102 in a slot in the loweredge of the corresponding interposer 95. Such interposer will then beadvanced to such a position that depression of the member 99 will effectdepression of the interposer and consequently of the correspondingpunch. A

Upon movement of any of the internosers, a common or universal member104 (Fig. 6) will be actuated and move a link 108 (Fig. 1) in contacttherewith in a direction to close contacts 223 (Fig. 9) to complete acircuit through a punch magnet 115. The latter thereupon attractsarmature 117 which through link 120 rocks bell crank 121 to drawpunching, it will swing a universal frame 132 about ashaft 133 andthrough suitable connections swing a dog 134 (Fig. 7) about a pivot 135into engagement with the rack 48 to prevent movement thereof by the gear84 dog 134 will be lifted and the rack 48 and the card carriage 7 willadvance one tooth to permit punching in the next column of the 1 card.

The escapement mechanism just referred to-is of the same general natureas that'disclosed in the patent to Schaafl, No. 1,426,223, grantedAugust 15,1922. 1

The operation of the punches may be controlled bymeans of the duplicator9 which causes selector magnets 144 (Figs. 6 and 9) to be actuated inaccordance with the perforations of a pattern card or previously punchedcard 3 which is arranged for punching in 45 di fi'erent columns. Theseselector magnets are twelve in number and operate the ten numeral he sand two keys, one being marked X and the other being blank, arranged tooperate the two punches .at the end of the row farthest from theoperator.

' Such operation of the keys controlled by the selector magnets maybeeffected by means of levers 145 having at their ends in one directionrounded heads 146 extending into slots in the shanks of the keys to becon- 1 trolled and extending in the other direction substantiallyhorizontally into the casing 140 for the selector magnets, upwardly to aplane above the cores 147 of the magnets and then rearwardly differentdistances to be pivoted to brackets .148 extending downwardly from aplate 149 rigidly-supported on the main frame. As indlcated in Figs. 3'and 6,

these brackets are arranged in three rows 4 corresponding-to the rows ofthe magnets and the rows of keys actuable thereby. Adjustably attachedto each of these levers is an armature 150 for cooperation with thecorresponding magnet.

Extending from one end of each magnet coil is a wire 151 (Figs. 2 and 9)with an insulating cover and these wires are gathered together in acable 152 which is led through a cable conduit 153 and down through thetable 74a of the duplicator and between the table and abottom plate 154.Here the cas ng of the cable ends and the wires 151 are fanned out andconnected bynuts 155 to the lower ends of twelve binding posts 156arranged in the same order as the magnets 144 and mounted in aninsulating plate 157 (Fig. 4). The

other ends of the magnet coils are connected through a suitable sourceof power to another wire 151a (see Fig. 9) which'is also included inthecable 152 and connected by nuts 155 with a thirteenth binding post156' spaced from the other binding posts156 as seen at the 'left'inFig. 1. Immediately above-each binding post 156 is a tube or guide 158mounted in a second insulating plate 159. These guides 158 are slightlycontracted at their tops to retain balls or analyzing contacts 160 andthese contacts are urged'to the upper ends of the guides by springs 161interposed between the balls and the heads of the binding posts. i

The insulatin plate 159 extends completely across the uplicator andimmediately above the contacts 160 is a roller 162 having a c lindricalcasing 163 of conducting materia such as any suitable metal mounted on anon-conducting tubular member 164 carried by bushings 165 on .a shaft166.! When a pattern or master card 3P is in the duplicator it will passbetween the roller 162 and all of the contacts 160'except the one to theleft of Fig. 9 which'is always in contact with the cylindrical casing163 when the roller 162 is in working position. It will be evident thatwhen there are no perforations in the portion of the pattern cardbetween the roller 162 and the ball contacts 160 none of the selectormagnets will be energized. When, however, a perforation in the patterncomes into positionover one of the contacts, the circuit of one of theselector magnets will be closed and the corresponding punch operated.

The shaft 166 is mounted in opposite sides of a frame or contact box 167which has at opposite ends ears 168 or the like ivoted to the table ofthe duplicator by suita le means such as screws 169 (Fig. 4 Extending tothe left (Fig. 3) from the rame 167 .is a resilient plate 170 which maybe held down by a latch 171 during'normal operation against the actionof'a spring 172. In-addition to the plate 170 provision .is made ofanother plate 17 3 to hold a pattern card in proper position.

This plate 173 is attached to the table 7 4a at its end remote from theroller 162 "and extends substantially to the roller 162.

When the card carriage 7 is in the position shown in Fig. 3, the latch171 ma be moved to ineffective position thereby a lowing the frame 167to be swun by the spring 172 from the position shown inTigs. 3 and 4 tothe position shown in Fig. 2'. The pattern or master card 3P may then beconveniently placed on the card carriage by first placing the right handend thereof. beneath the roller and the left hand end of the plate 173.The card carriage may then be moved to the right preparatory to startingthe punching'and the frame 167 and plate 17 0 may then be swungdownwardly to the ositions shown in Fig. 4 and there retained y thelatch 171.

Referringto Fig. 9, it is broadly stated that this circuit diagram maybe said to include a punch magnet circuit 262 shown by heavy lines and aduplicator circuit shown by light lines and designated by'referencecharacters 151a, 151,260 and 261. It will be understood that at eachpunch operation, whether by'means of depression of the keys or by theenergization of the selector magnets 144 under the control of theduplicator, contacts 223 will be closed by the action of the interposersin the manner heretofore described to bring about the eneigization ofthe punch magnet 115. Immedi tely after this punch magnet 115 isenergized, contacts 223 are opened by member 126,elevating link 108 freeof the universal member 104. Thereafter, contacts 223 reopen under theirown resilienc The foregoing describes the opera- 1 tion 0 the punchmagnet circuit. A

The 0 eration of the duplicator circuit may be t us described. Theduplicator circuit is automatically closed through the pattern card 3Pwhen holes in the card permit balls'160 to establish contact with roll162."

151, a selector magnet 144, wire 260, and back. to source through wire261.

The selector. magnet 144 is thus energized under the control of thepattern card and brings about the selection and operation of theassociated punch in the manner previously described.v

As previously explained in connection with the description of theoperation of the punch magnet circuit 262, contacts 223 areautomatically opened after each depression of the punch.

' Upon reference to Figs. land 4 it will be seen that the contactstructureffixed to the table 74a is such as to facilitate assembly ofthe parts. The guide tubes 158 may readily be placed in the insulatingplate or member 159, and the binding posts 156 in the insulating plate157. The balls or contacts 160 may 'then be placed in the tubes 158, thesprings 161 inserted in the tubes,'the plates 157 and 159 placed againsteach other in proper relation, and the assemblage secured to the lowerside of the table 7 4a by means of screws 242.

The machine may be operated in various ways such as the following. Apack of cards 3 may be placed in the magazine and withdrawal therefromone by one b means of the picker is effected by means 0 the handle 2which serves to operate the rod 34. Upon movement of the rod 34 to theleft with the picker 4 the clutch 44 will be closed and the cardcarriage moved to the'right far enough i for the card advanced by thepicker to lift the device 70 and move under the same tosuch an extentthat the finger 244 of the device 7 0 will reston the card, the otherend of the card being engaged by the device 72r The card carria e 7 willthen be held, in its initial position orpunching, by the stepping of theteeth on the two members.- 7

When the duplicator 9 is to be used, the card carriage is moved to itsextreme leftward position and, with the parts of the duplicatorpositioned as in Fig. 2, a punched card or pattern card 3P is placed inengagement with the devices 74 and 76, being inserted from the leftbetween the roller 162 and contacts 160 and beneath the plate 173. Theframe or box 167 is then swung) downwardly and the end of the plate 170rought against the beveled upper edge of the'latch 171 to swing thelatter about its pivot 249 against the action of a spring 250 which,when the plate 17 0 reaches the proper position, brin s the hooked endof the latch over e aging said carrier for normally yieldably ho dingthe carrier and its contact apart from the end 0 the plate. After thisstage of the o eration a card should be introduced into 1; e punchingmechanism by means of the picker 4.

Each time a, circuit is completed through the duplicator card 3]? andpunching effected, the pawl 86 is released from escapement rack 85 andthe carriage 7 moves to the left (Fig. 3). When a card 3 is completelyperforated, the carriage 7 and the pattern card 3P is returned to theleft. During the movement of the card 3]? in either direction thenon-frictional engagement of the card with roller contact 162 andspherical contacts 160 facilitates the movement of the card. If inclinedreading brushes or feelers, such as are ordinarilyused in the tabulatingart were employed, the return of the card would be interfered with andthe brushes injured.

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing I from thespirit of the invention. It is the intention therefore to be limitedonly as indicated by the scope of the following claims:
